The answer to 'why is my pipe clogged' is that pipes can become clogged for a variety of reasons, such as buildup of hair, soap scum, food particles, or other debris. Common symptoms include slow draining, gurgling sounds, or water backing up in sinks, tubs, or toilets.
Some solutions you can try include using a plunger to dislodge the clog, using a drain snake or auger to break up the blockage, or using a chemical drain cleaner. However, if the clog is severe or the issue persists, it's best to call a professional plumber who can properly diagnose and fix the problem.
